IMPACT OF PYROLYSIS TEMPERATURE AND BIOMASS TYPE ON PHYSICOCHEMICAL PROPERTIES OF BIOCHAR ON SOIL FERTILITY
Authors: INNOCENT IGIRANEZA, PROTOGENE HAKIZIMANA, IMMACULEE BAYISENGE
Abstracts: Biochar is pyrogenous, organic material synthesized through pyrolysis of different biomass (plant or animal). Main biochar applications include: pollution remediation due to high CEC and specific surface area, soil fertility improvement and carbon sequestration due to carbon and ash content etc. Pyrolysis temperature and biomass type used to prepare biochar affect the physicochemical characteristics of produced biochar, and when applied as soil amendment shows a range of results. In this study, Different biochars were prepared from different biomass types, namely Corn cobs (Zea mays), eucalyptus tree branches (Eucalyptus globulus), potato peels (Solanum tuberosum) at and sorghum tassels (Sorghum bicolor) at temperature range of 6000C-7000C. However, eight biochars were prepared where four biochars were prepared in open environment and other in furnace. The impact of temperature and biomass type on variability of physicochemical characteristics of obtained biochars were evaluated through measuring pH, electrical conductivity(EC), total dissolved solids and moisture content and Moreover, the physicochemical properties of biochar determine application of this biomaterial as an additive to improve soil fertility. The objective of study was to evaluate the impact of biomass type and pyrolysis temperature on physicochemical properties of biochar on soil fertility. The results of moisture content of different biomass types, namely Corn cobs (Zea mays), eucalyptus tree branches (Eucalyptus globulus), potato peels (solanum tuberosum) and sorghum tassels (Sorghum bicolor) are 59.97±0.03%,39.87±0.03%,79.65±0.04% and 23.75±0.03%respectively. The pH in furnace was :9.90, 10.03, 9.95, 10.03 respectively; EC :1850, 1248, 4660, 5400; TDS:989, 651, 2630, 3110 respectively and in open environment was :11.20, 11.06, 10.04, 11.92; 2640, 2630, 7590, 5720; 1401, 1407, 4260, 320 in pH, EC, TDS respectively.All results reported with negative values are not detected in samples (ND)

STRESS, ANXIETY, AND DEPRESSION AMONG NURSING STUDENTS: BASIS FOR AN INTERVENTION PROGRAM
Authors: VANESSA N. FERNANDEZ, MARICHU P. DIENDO
Abstracts: Nursing school is challenging and overwhelming. It has been well-documented that nursing students worldwide experience stress, anxiety, and depression throughout their formal education and clinical training. The main objectives of the present study were to determine the levels of stress, anxiety, and depression among nursing students in General Santos Doctors' Medical School Foundation, Inc. and to develop an intervention program based on the results of the study. A descriptive survey research design was conducted among a randomized sample of 163 nursing students in General Santos Doctors' Medical School Foundation, Inc. from March to April 2021. Data collection was performed using the Depression Anxiety Stress Scale (DASS-42). Out of 163 identified randomized samples, 146 nursing students participated in the study; most of them were within the 17–20 year old age bracket and in their first year. Furthermore, the majority of the respondents experienced stress, anxiety, and depression, which ranged from mild to extremely severe levels. Results also showed that among the three psychological health issues, anxiety was the most prevalent. The Counselor CARES (Caring About Restoring Students' Well-being) intervention program, a CBT-based intervention program, has been developed to address the mental health problems of students, specifically stress, anxiety, and depression.

Authors: MD. SABUR UDDIN; MD. ZAKARIA HOSSAIN
Abstracts: In this article, we have developed some characterizations of Lie and Jordan ideals of simple and semi-prime gamma rings by means of involution mapping. Several properties of arbitrary gamma rings related to this work are also established here.

COMPARATIVE CYTOTOXICITY OF ROASTED COFFEA ARABICA AND LEUCAENA LEUCOCEPHALA SEED EXTRACT USING BRINE SHRIMP LETHALITY ASSAY
Authors: DANTE A. BARBERO
Abstracts: Coffee comprises compounds that contribute to the flavor and bioactivity of the brew. The complex reaction modifies the coffee’s chemical composition during roasting at high temperatures, with some beneficial compounds and some created. The Leucaena leucocephala is locally termed as “Ipil-ipil tree,”. Findings have revealed that it has antidiabetic and antioxidant properties. This study aims to analyze, determine and compare the level of cytotoxicity of Coffea arabica and Leucaena leucocephala using the brine shrimp lethality assay and validate the nutritional value, food edibility, and medical benefits of Leucaena leucocephala to be considered as one of the substitutes for coffee consumption. The general findings revealed that C. Arabica has (LC50) 10584.75 and L. leucocephala has (LC50) 1100.286, which indicates that both compounds have no toxicity. These findings are based on Meyers and Clarkson toxicity indexes. This study recommends that L. leucocephala seeds could be eaten and substituted for coffee, but consumption should be in moderation.
